Description

Technical Field

[0001] This invention relates to, and more particularly to, a wastewater classification, purification, and recycling device for glass processing. Background Technology

[0002] The glass processing steps, such as cutting, edging, and drilling, generate a large amount of wastewater. This wastewater contains pollutants such as glass powder, abrasive residue, and oil. Direct discharge of this wastewater easily leads to water waste and environmental damage. Therefore, it is necessary to purify and recycle the wastewater. Current glass processing wastewater treatment devices mostly use single purification processes, which are insufficient for removing different types of pollutants and cannot meet the water quality requirements for reuse in glass processing. Some multi-stage treatment devices also suffer from cumbersome structures and poor integration, limiting their practicality.

[0003] Existing glass processing wastewater treatment devices suffer from poor solid-liquid separation, making it difficult to completely remove fine suspended solids, and the filter components are prone to clogging, affecting purification efficiency. The oil removal and adsorption processes are not properly connected, and oil stains easily contaminate the adsorption materials, reducing the deep purification effect. At the same time, the waste residue collection is not classified, which can easily cause secondary pollution and cannot meet the treatment needs of glass processing wastewater. Summary of the Invention

The filter plates are arranged coaxially and axially evenly outward to form an axially continuous and circumferentially uniform multi-layer filter channel. The filter pore diameter of the filter plates gradually decreases from the inside to the outside, and the filter pores on the outermost filter plate are all distributed in the upper half.

[0009] As a further preferred embodiment, the slag scraping assembly includes a drive plate, slag scraping plates, a power motor, and a slag suction pump.

[0010] As a further preferred embodiment, the oil removal assembly includes an oil removal tank, an electric telescopic rod, and an oil skimmer. The oil removal tank is disposed within the housing, and the electric telescopic rod is disposed within the housing.

Detailed Implementation

[0025] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages). Example

[0026] A wastewater classification, purification, and recycling device for glass processing, such as... Figure 1-8 As shown, it includes an outer shell 1, a pretreatment mechanism 2, a primary purification mechanism 3, a secondary purification mechanism 4, a reuse mechanism 5, and a waste collection box 6. The mechanisms are connected in sequence to form a closed-loop graded purification and circulation circuit. The pretreatment mechanism 2, the primary purification mechanism 3, the secondary purification mechanism 4, and the reuse mechanism 5 are all made of corrosion-resistant materials, suitable for the corrosive environment of glass processing wastewater. Sealing components are provided at the connection points between the mechanisms.

[0027] like Figure 2 and Figure 3As shown, the pretreatment mechanism 2 includes a feed hopper 21, an interception component 22, and a buffer chamber 23. The feed hopper 21 is connected to the buffer chamber 23. The interception component 22 is located at the connection between the feed hopper 21 and the buffer chamber 23 and is used to intercept large glass fragments and impurities in the wastewater. The interception component 22 includes an interception net 221, a reciprocating drive component 222, and a scraper 223. The interception net 221 is detachably connected to the feed hopper 21. The mesh size of the interception net 221 is adapted to the particle size of large impurities in the glass processing wastewater, and the interception net 221 is gradually inclined downward from back to front to increase the effective interception area, so that large impurities will naturally slide down under gravity and are not easy to accumulate in the same position on the net surface. The reciprocating drive component 222 is located on one side of the feed hopper 21, and the output end of the reciprocating drive component 222 is fixedly connected to the scraper 223. The scraper 223 is in contact with the surface of the interception net 221, and the interception net 221 accurately intercepts large glass fragments and impurities in the wastewater. Simultaneously, the scraper driven by the reciprocating drive component cleans impurities on the screen surface in real time, preventing screen blockage, ensuring smooth wastewater flow, and reducing the processing burden of subsequent purification mechanisms; the buffer chamber 23 is equipped with a stirring assembly 24 to uniformly mix the wastewater and prevent pollutants from settling and clogging. The stirring assembly 24 includes a stirring shaft 241, stirring blades 242, and a stirring motor 243. The stirring shaft 241 is rotatably connected to the buffer chamber 23, and the stirring blades 242 are evenly distributed on the stirring shaft 241. The stirring motor 243 is installed on the buffer chamber 23, and the output end of the stirring motor 243 is connected to the stirring shaft 241. A metering pump is installed between the buffer chamber 23 and the primary purification mechanism 3. By stirring the wastewater, the pollutants are evenly dispersed, preventing glass powder and fine suspended matter from settling and clogging the pipeline. At the same time, the wastewater can be fully mixed with the purification auxiliary agent to improve the subsequent purification effect. It can also allow the wastewater to flow smoothly to the primary purification mechanism 3, ensuring smooth water flow in the pretreatment stage. like Figure 2 and Figures 4-6As shown, the primary purification mechanism 3 is connected to the buffer chamber 23. The primary purification mechanism 3 contains a filter assembly 31 and a scraper assembly 32. The filter assembly 31 filters fine glass powder and suspended particulate matter in the wastewater. The scraper assembly 32 works in conjunction with the filter assembly 31 to scrape off the waste residue adhering to the surface of the filter assembly 31, preventing clogging. The filter assembly 31 includes a fixed base 311, a support frame 312, and a filter plate 313. The fixed base 311 is fixedly connected to the outer casing 1, and uniformly distributed... The supporting frame 312 is equipped with filter plates 313. The filter plates 313 are arranged coaxially and axially uniformly outward to form a multi-layered filtration channel that is axially continuous and circumferentially uniform. The pore size of the filter plates 313 gradually decreases from the inside to the outside, realizing step-by-step fine filtration of fine glass powder and suspended particles of different sizes in the wastewater, and completing efficient solid-liquid separation. The filter holes on the outermost filter plate 313 are all distributed in the upper part, so as to allow the purified wastewater in the upper layer to overflow naturally and avoid disturbing the bottom water flow. The filter plate 313 is separated into fine waste residues. The scraping assembly 32 includes a drive plate 321, a scraper plate 322, a power motor 323, and a suction pump 324. The drive plate 321 is rotatably connected to the outer casing 1. The evenly distributed scraper plates 322 are fixed on the drive plate 321. The scraper plates 322 are spiral-shaped and can achieve spiral full-area scraping of the filter plate 313 without cleaning dead corners. At the same time, the spiral structure can form a downward guiding force during scraping, guiding the waste residue to slide smoothly down the filter plate 313, improving the waste residue efficiency. The scraper plates 322 are attached to the surface of the filter plate 313. The outer casing 1 is equipped with a power motor 323, the output end of which is connected to the transmission wheel of the drive plate 321. The fixed base 311 is provided with a slag discharge hole corresponding to the filter channel. The fixed base 311 is also provided with a slag suction pump 324. One end of the slag suction pump 324 is connected to the slag discharge hole in the fixed base 311, and the other end is connected to the waste residue collection box 6. The core purification structure is formed by the cooperation of the filter component 31 and the scraper component 32, which effectively and continuously ensures the solid-liquid separation efficiency of the purification and reduces the pollutant load in the subsequent purification process from the source.

[0028] like Figure 7 and Figure 8As shown, the secondary purification unit 4 is connected to the primary purification unit 3. The secondary purification unit 4 is internally equipped with an oil removal component 41 and an adsorption component 42. The oil removal component 41 is used to separate oil from the wastewater, and the adsorption component 42 is used to adsorb residual pollutants and odors from the wastewater. The oil removal component 41 includes an oil removal tank 411, an electric telescopic rod 412, and an oil skimming plate 413. The oil removal tank 411 is located inside the outer casing 1, and the electric telescopic rod 412 is located inside the outer casing 1. The telescopic end of the electric telescopic rod 412... A skimming plate 413 is slidably connected. An elastic element, a spring, is provided between the skimming plate 413 and the telescopic end of the electric telescopic rod 412. A limit frame 414 is provided inside the outer casing 1. The skimming plate 413 is slidably connected within the limit frame 414, and the sliding trajectory of the skimming plate 413 within the limit frame 414 is a parallelogram. A spring pin 415 is slidably connected to the skimming plate 413. A limit groove is provided inside the limit frame 414, and the limit groove and the spring pin 415 are in a limiting sliding engagement. The oil removal tank 411 is connected to the waste residue collection box 6. The bottom of the oil removal tank 411 is provided with a through hole. The oil removal tank 411 is connected to the adsorption component 42 through the through hole. The oil skimming plate 413 is driven by the electric telescopic rod 412 to accurately scrape off the floating oil on the surface of the wastewater in the oil removal tank 411, so as to avoid oil pollution of the subsequent adsorption packing and reduce the adsorption effect. The adsorption component 42 includes a baffle plate 421, an adsorption frame 422 and an adsorption packing 423. The baffle plate 421 is uniformly fixedly installed in the outer shell 1 to deflect and block the wastewater after oil discharge, prolong the flow path and residence time of the wastewater in the adsorption area, improve the adsorption and purification effect of residual pollutants and odors, and at the same time buffer the water flow impact speed to avoid the water flow directly hitting and causing the adsorption packing to be lost or locally eroded and caking, thus ensuring the stable purification efficiency of the adsorption component. Located downstream of the oil removal component 41, the adsorption frame 422 is slidably connected to the outer shell 1, and the adsorption packing 423 is filled inside the adsorption frame 422. The adsorption packing 423 is made of activated carbon adsorption material.

[0029] like Figure 7 As shown, the reuse mechanism 5 includes a water storage chamber 51 and a conveying component 52. The water storage chamber 51 is connected to the secondary purification mechanism 4 and is used to store purified wastewater that meets the standards. The conveying component 52 is connected to the water storage chamber 51 and is used to convey the purified wastewater to the glass processing equipment to achieve recycling. The conveying component 52 includes a conveying pump and a conveying pipeline. The conveying pump is connected to the water storage chamber 51, and one end of the conveying pipeline is connected to the conveying pump, while the other end is connected to the water inlet of the glass processing equipment. A control valve is installed on the conveying pipeline. The purified wastewater meets the standards and is stored in the water storage chamber 51. Then, the conveying component 52 accurately conveys the wastewater to the glass processing equipment, which greatly reduces the water cost of glass processing production. At the same time, the water storage chamber 51 can temporarily buffer the water to adapt to the intermittent water demand of the processing equipment and ensure the stability and continuity of water supply.

[0030] Waste collection box 6 is connected to pretreatment unit 2 and primary purification unit 3 respectively. It is used to collect large particulate impurities intercepted by interception component 22 and fine waste residue scraped by scraping component 32. Waste collection box 6 is equipped with slag guiding pipe, which is connected to interception component 22, scraping component 32 and oil removal component 41 respectively. Waste collection box 6 is equipped with partition plate to separate large particulate impurities, fine waste residue and oil stains. By centrally collecting and intercepting various impurities, waste residue can be classified and collected and disposed of, avoiding secondary pollution caused by mixed storage and improving the convenience of subsequent recycling and cleaning.

[0031] Wastewater generated during the cutting, edging, and drilling processes in glass processing is first introduced into the pretreatment mechanism 2 through the feed hopper 21. When the wastewater flows through the interception component 22 in the feed hopper 21, the interception net 221 directly intercepts large glass fragments, abrasive blocks, and other impurities in the wastewater. At the same time, the reciprocating drive component 222 works continuously, driving the scraper 223 to slide back and forth along the surface of the interception net 221, scraping off large impurities attached to the interception net 221 in real time to prevent the interception net 221 from clogging. The scraped-off large impurities enter the corresponding chamber of the waste collection box 6 directly through the slag guide pipe.

[0032] After being intercepted, the wastewater enters the buffer chamber 23. The stirring motor 243 starts and drives the stirring shaft 241 to rotate. The stirring blades 242 rotate synchronously with the stirring shaft 241 to uniformly stir the wastewater in the buffer chamber 23, so that the pollutants in the wastewater are evenly dispersed, and the glass powder and fine suspended matter are prevented from settling at the bottom of the buffer chamber 23 and clogging the subsequent pipeline. If purification auxiliary agents need to be added, they can be added in this step. The stirring component 24 can fully mix the auxiliary agents with the wastewater, improve the subsequent purification effect. The pretreated wastewater in the buffer chamber 23 enters the primary purification mechanism 3 under the action of the metering pump.

[0033] After entering the primary purification unit 3, the wastewater flows through the multi-layer filtration channels of the filter assembly 31. The filter plates 313 are arranged coaxially and evenly outward, with the pore size decreasing progressively from the inside to the outside, achieving progressive fine filtration of the wastewater. This sequentially traps glass microparticles and suspended particles of different sizes in the wastewater, completing solid-liquid separation. During the filtration process, the power motor 323 starts, driving the drive plate 321 to rotate. The spiral scraper plate 322, fixed to the drive plate 321, rotates synchronously with the drive plate 321, and the scraper plate 322 remains in contact with each layer of filter plates 313. 13. Surface adhesion enables the scraping of fine waste residues adhering to the surface of filter plate 313, preventing filter plate 313 from clogging and ensuring stable filtration efficiency; the scraped fine waste residues fall into the bottom of fixed seat 311 under the action of spiral scraper plate 322, and the slag suction pump 324 starts to transport the fine waste residues in fixed seat 311 to the corresponding chamber of waste residue collection box 6 through slag discharge hole and slag guide pipe, realizing the rapid collection of fine waste residues. Under the overflow action of the filter holes in the upper half of the outermost filter plate 313, the wastewater with suspended solids removed flows into the secondary purification mechanism 4 by gravity.

[0034] Wastewater, after having suspended solids removed by the primary purification unit 3, flows by gravity into the oil removal component 41 of the secondary purification unit 4. The wastewater collects in the oil removal tank 411, and the floating oil naturally rises to the surface of the wastewater. The electric telescopic rod 412 is activated, causing the skimming plate 413 to slide horizontally along the limiting frame 414. The spring pin 415 cooperates with the limiting groove to limit the sliding of the skimming plate 413. When the telescopic end of the electric telescopic rod 412 retracts, the electric telescopic rod 412 causes the skimming plate 413 to move to the right, skimming the oil on the surface of the wastewater to the right, until the skimming plate 413 moves to its rightmost limit position. The oil skimmer 413 moves upward and away from the water surface under the action of the limiting frame 414 until the spring pin 415 moves into the limiting groove. The spring pin 415 extends under the action of the spring to limit the oil skimmer 413. When the telescopic end of the electric telescopic rod 412 extends, the oil skimmer 413 moves to the left and stays away from the water surface to prevent the oil skimmer 413 from pushing the oil away to the left again until the oil skimmer 413 moves to the initial position. By repeating the above steps, the oil on the surface of the water is skimmed off. The skimmed oil enters the independent chamber of the waste slag collection box 6 through the slag guide pipe for separate storage.

[0035] After oil removal, the wastewater flows into the adsorption assembly 42 area through the through hole at the bottom of the oil removal tank 411. The wastewater forms a baffle flow under the obstruction of the baffle plate 421, which prolongs the water flow path and residence time, while reducing the impact force of the water flow. This allows the wastewater to fully interact with the activated carbon adsorption packing 423 in the adsorption frame 422. The adsorption packing 423 efficiently adsorbs residual organic matter, cleaning agent residue, and odor pollutants in the wastewater, achieving deep purification of the wastewater. The adsorption frame 422 has a sliding connection structure. If the adsorption packing 423 becomes saturated, the adsorption frame 422 can be directly pulled out for packing replacement, making the operation convenient.

[0036] After being deeply purified by the secondary purification unit 4, the qualified wastewater flows by gravity into the water storage chamber 51 of the reuse unit 5 for storage. When the glass processing equipment needs water, the control valve of the conveying component 52 is opened and the conveying pump is started. The purified wastewater in the water storage chamber 51 is conveyed to the water inlet of the glass processing equipment through the conveying pipeline, realizing the recycling of wastewater and greatly saving production water resources.

[0037] Throughout the purification and recycling process, the waste collection box 6 collects large particulate impurities from the pretreatment stage, fine impurities from the primary purification stage, and oil stains from the secondary purification stage through multiple slag guide pipes. The internal partitions separate the various pollutants, preventing secondary pollution caused by mixed disposal. The waste collection box 6 can also be cleaned periodically according to actual production needs. Meanwhile, the pretreatment mechanism 2, the primary purification mechanism 3, the secondary purification mechanism 4, and the reuse mechanism 5 are all made of corrosion-resistant materials, and sealing components are installed at the connection points of each mechanism to effectively adapt to the corrosive environment of glass processing wastewater, prevent wastewater leakage, and extend the overall service life of the device.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
